im curious about making my own chicken feed, but know its not that simple. my chickens free range for about 5 hrs a day, almost everyday. right now they are actually eating a sporting bird feed, which i want to change now that i seperated my guineas. what feed should i change them to for my laying hens and roo? what % protein? if i continue to buy rather than make my own. and can anyone tell me how they make thier own mash? ingredients and whatnot? thanks!
